The present disclosure provides a device and method for circuit testing and a display device applying the same. The device for circuit testing includes a detection circuit configured to detect whether a display panel and a printed circuit board are electrically conductive, wherein the detection circuit includes: a first metal redundant track configured to input an electrical detection signal; a second metal redundant track bonded to the first metal redundant track via a first anisotropic conductive film; a third metal redundant track electrically connected to the second metal redundant track; and a fourth metal redundant track bonded to the third metal redundant track via a second anisotropic conductive film.
